lib: Update stm32f1 code to version 1.8.0
Update the stm32f1 code to the latest from ST. Merge the lib/cmsis-stm32f1/ and lib/hal-stm32f1/ into a single lib/stm32f1/ directory. Document all the differences from the pristine upstream code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

##### How to use this driver #####
|

==============================================================================
|

[..] This driver provides functions to use EVENTOUT Cortex feature
|
||||
(#) Configure EVENTOUT Cortex feature using the function HAL_GPIOEx_ConfigEventout()
|
||||
(#) Activate EVENTOUT Cortex feature using the HAL_GPIOEx_EnableEventout()
|
||||
(#) Deactivate EVENTOUT Cortex feature using the HAL_GPIOEx_DisableEventout()
